Product Details
An overhead line tube (often called an Insulcover) is a medium-voltage protective sleeve used to insulate bare overhead conductors. Primary Purpose: To prevent electrical outages caused by accidental contact from wildlife, birds, or tree branches. Key Features: Material: High-quality non-tracking polyolefin or silicone rubber. Voltage Ratings: Typically rated for 11kV, 22kV, and 33kV systems. Durability: Engineered to be UV-stabilized, weather-resistant, and flame-retardant for long-term outdoor exposure. Installation: Designed for easy, manual installation over existing lines without specialized tools; some versions are interlocking for a secure fit. Conductor Tube (Rigid Busbar)A conductor tube refers to a rigid tubular busbar typically used in outdoor high-voltage substations. Primary Purpose: To act as a central junction where multiple incoming and outgoing electrical currents converge, providing a high current-carrying capacity for systems up to 765kV. Key Features: Material: Predominantly made of Aluminium or Aluminium Alloy because of its superior conductivity-to-weight ratio and cost-effectiveness compared to copper. Design: The tubular shape provides high mechanical strength to handle wind and ice loading while minimizing corona discharge losses due to its larger effective radius. Cooling: Benefit from natural air circulation, allowing them to operate at higher ampacities without overheating. Support: These are supported by rigid post insulators rather than being suspended like standard flexible conductors.
